CZ3D

[empty_pockets]

Why is this CZ model a favorite over all other CZ models...Never used the 3D, but using the 6a, this model would be a tough one to beat...

I think because of certain older coins that will high tone on the 3D. I have had a cz-5 and 3D in the last couple years and liked the Cz-5 better.

Why would you choose the CZ-5 over the CZ-3D....curious ??
Can you shed some light on it...

Thanks.

Not that I would choose the cz3d over the cz6a, I tried and like the detector and have yet seen the cz3d to give it a try...This is why I asked the question not knowing the pro and con between the two...

The CZ3D looks awesome. It can detect on land great and then its a nonwaterproof CZ21 when on the beach. Plus there are guys out there that mod them to make them crazy deep. If I were buying new right now I would probably get the 3D over the 21 because I use the DF when I water hunt...but I got the 21 when it was only $300 more new than the 3D

adambomb ... who mods the cz3d...??

NASA Tom the guy who runs http://www.dankowskidetectors.com/

NASA Tom doesn't exactly mod them, he just re-tunes them back to original specs, which may or may not increase the depth of that particular machine. I think he can also tune a cz 5 or 6 to behave like a 3D in enhanced mode.

Yes!

There has been a lot of information posted in various places indicating that, on a functional CZ, there is little that can be done to affect detection depth. Tuning a CZ is reported to be all about what specific targets sound off with what tone and with what ID. The standard nickle range is very narrow, the 3D enhanced setting opens it up a bit.

I have not attempted to tune one, but the CZ 20 I have has been tuned to make a nickle sound mid-tone and to not sound on an intact zinc penny when in disc mode. Eaten up zincs do sound off. Of course auto-tune sounds on all. With a meter, I like the standard tune on my CZ 6A. The 6A lets me see the high tone nickle ID on the meter. With either the 6A or 20, I pretty much dig all mid and high tones as well as low tones that bounce ... but aren't the iron wrap around bounce.

A "Tom certified" CZ means he tested it set up to his specific control (repeatable) settings in his controlled test environment and certifies that he deems the detector detects a specific coin (dime) at a specific air test distance. He also sets up the tone and ID per his standards that may or may not be the criteria the factory uses; but they are probably close. I think it was reported a couple months back that a "Tom certified" detector sold at a little bit of a premium. It turned out that particular CZ was certified as 8.5 inches. I've seen Tom report that a "good" CZ will certify to about 12 inches and a hot one a little better.

So there is a little bit of fuzziness in how to interpret certified, good and hot. Buyers beware of that. And consider multiple sources of information! How I interpret what I read or what my detector is telling me may be different than how anyone else interprets things.

Edit to add something to stay on the original topic. My opinion on the perception that the CZ3d is more desired than an older version is that it is NEWER and is STILL in production. That almost makes the older CZ's obsolete. But I'll hang onto my old ones for a while longer!

So anyone mod a cz up to be waterproofed? How well does the cz 3d performing salt water?

On the salt sand, it performs equally to the CZ21.

When Tom Dankowski certifies and calibrates the cz-3d, the depth is measured in his mild Florida soil, not an air test.

Depth increases I've seen on Tom tuned units range from nothing to half an inch.

The cz-3d operationally is very similar to the cz-5. The cz-3d has a fourth (foil) tone the cz-5 doesn't. Also, the cz-3d high tone parameters have been adjusted (when in enhance mode) to sound off on more older coins.

From unit to unit, depth and quality of tuning on the cz-3d varies more than than I've ever heard of with any other detector.

12 inches, give or take a few tenths, is the benchmark for a hot Dankowski unit with the stock 8" coil. The deepest of the units I've ever seen tuned to the 8" coil was 12.4". The shallowest, 8.3".

Does the CZ21 have this much variation as well?

 

[marcomo]

I don't think any mass produced detector ever made has as much variance as the cz-3d.

A stable and deep, properly tuned cz-3d is a joy to use in moderate or lighter iron and/or trash areas.

I know the CZ3D is dood. I have a 6a and a AT Pro and I've been using the 6a more lately. I've always been happy with the 6a, does a good job on most everything I hunt for . Been trying to sell my 3D, I'm 90 and just don't get out as much as I used to.

 

[mrb1268]

Old geezer, is it still available and do you know the max. depth on your CZ3D?
